2.7 Seek time
Seek measurements are taken with nominal power at 25°C ambient temperature. All times are measured using
drive diagnostics. The specifications below are defined as follows:
• Track-to-track seek time is an average of all possible single-track seeks in both directions.
• Average seek time is a true statistical random average of at least 5,000 measurements of seeks between
random tracks, less overhead.
*Seek times (msec) Read Write
Typical Max Typical Max
Track-to-track 2.0 2.5 3.0 3.5
Average 16.0 17.0 19.0 22.0
Full-stroke 26.0 27.0 29.0 32.0
Average latency 8.3
*Measured in performance mode
Note. These drives are designed to consistently meet the seek times represented in this manual. Physical seeks,
regardless of mode (such as track-to-track and average), are expected to meet or exceed the noted values.
However, due to the manner in which these drives are formatted, benchmark tests that include command
overhead or measure logical seeks may produce results that vary from these specifications.

Time to ready Typical Max

ST1 Series Product Manual, Rev. A 7
2.9 Power specifications
The drive receives DC power (+3.3V or +5V) through the CompactFlash interface connector for ST650211CF
and ST625211CF models, and (+3.3V only) through the Flex interface connector for ST650211FX and
ST625211FX models.
2.9.1 Power consumption
Power requirements for the drives are listed in the table on page 9. Typical power measurements are based on
an average of drives tested, under nominal conditions, using +3.3V and +5.0V input voltage at 25°C ambient
temperature.
• Spinup power
Spinup power is measured from the time of power-on to the time that the drive spindle reaches operating speed.
• Seek mode
During seek mode, the read/write actuator arm moves toward a specific position on the disc surface and does
not execute a read or write operation. Servo electronics are active. Seek mode power is measured based on
three random seek operations every 100 msecs. This mode is not typical.
• Read/write power and current
Read/write power is measured with the heads on track, at the moment while the head is writing/reading
from/to disc. It is performed with 100% duty cycle of write/read operation.
• Idle mode power, low
Spindle motor is working normally with actuator unloaded to the parked position.
• Standby mode / Sleep mode
During Standby mode, the drive accepts commands, but the drive is not spinning, and the servo and read/
write electronics are in power-down mode.

power to operational levels.

ST1 Series Product Manual, Rev. A 9
2.9.2 Conducted noise
Input noise ripple is measured at the host system power supply across an equivalent 15-ohm resistive load on
the +5 volt line.
Using 5-volt power, the drive is expected to operate with a maximum of 100 mV peak-to-peak square-wave
injected noise at up to 20 MHz.
Using 3.3-volt power, the drive is expected to operate with a maximum of 70 mV peak-to-peak square-wave
injected noise at up to 20 MHz.
Note. Equivalent resistance is calculated by dividing the nominal voltage by the typical RMS read/write
current.

2.9.4 Power-management modes
The drive provides programmable power management to provide greater energy efficiency. The drive features
the following power-management modes:
Table 3: Power management modes
Power modes Heads Spindle Buffer
Active (operating) Tracking Rotating Enabled
Idle, low power Parked Rotating Disabled
Standby/Sleep Parked Stopped Disabled
• Active mode
The drive is in Active mode during the read/write and seek operations.
• Low power idle mode
Drive enters Low Power Idle mode from Active Idle mode when the Advanced Power Management Level is
set above 80h and the Idle timer is reached at 2 seconds. Disc is spinning and head is parked and drive accepts
all commands and returns to Active mode any time disc access is necessary.
• Performance idle mode
The buffer remains enabled, and the drive accepts all commands and returns to Active mode any time disc
access is necessary.
• Standby/Sleep mode
The drive enters Standby mode when the host sends a Standby Immediate command. If the host has set the
standby timer, the drive can also enter Standby mode automatically after the drive has been inactive for a
specifiable length of time. The standby timer delay is established using a Standby or Idle command. In Standby
mode, the drive buffer is enabled, the heads are parked and the spindle is at rest. The drive accepts all
commands and returns to Active mode any time disc access is necessary.
• Standby timers
Each time the drive performs an Active function (such as read, write or seek), the standby timer is reinitialized
and begins counting down from its specified delay times to zero. If the standby timer reaches zero before any
drive activity is required, the drive makes a transition to Standby mode. In both Idle and Standby mode, the
drive accepts all commands and returns to Active mode when disc access is necessary.
